Jet Tools JJP-12 - Manual (Page 2)

Capacities
To make the JET JJP-12 Jointer-Planer as capable as it is versatile, the jointing and
planing width capacity is a full 12”. That capacity allows you to work with wider boards
without having to rip them down to fit common jointer
widths in the 6 to 8” range. Because both the jointer and
planer width capacities are the same, you can move
between those modes without having to add an additional
ripping step to the process.
The precision machined 3-knife cutter
head and feed roller system (planing
mode) make the JET JJP-12 effective.
3-Knife Cutterhead
The JET JJP-12 Jointer-Planer uses a large 2 ¾”-diameter
cutterhead fitted with three high quality knives for both
jointing and planing operations. The cutterhead turns at
5500 RPM for all operations. The knives are retained
with conventional wedge bars and have jacking screws
that make setting their height precisely much easier.
Because this cutterhead is used for both jointing and
planing, setting the knives one time is all that is required.
Changing Modes
From the beginning, along with accuracy, capacity and
durability, developing a fast, easy way to change
between jointing and planing modes was high on the
design criteria list. The JET JJP-12 Jointer-Planer
sports a very simple, tool-free hinge based system that
allows changing between jointing and planing modes
very quickly without having to remove any
components.
Changing from jointing to planing or
back on the JET JJP-12 is fast and
simple. Unlock the jointing deck, lift it to
its upright position, flip the dust collector
into planing position and engage the feed
rollers. It takes less time to do than to
describe! Going back to jointing is just as
fast.
A pair of locking levers on the cabinet sides release the
jointing bed which is then rotated up to expose the
planer section. Lifting the cast iron jointer bed
assembly (moves as one piece) is made easier because
of spring-assisted hinges that reduce that effort
substantially. A drop in lock at the hinge point secures
the jointer bed in the upright position.
